Introduction
This portfolio is a selection of work I produced for the Spatial Analysis module in Fall 2021.
The learning objectives for this course included displaying spatial data and relationships, visualizing places, mapping routes and networks, and creating interactive, web-based maps.
In addition to learning technical spatial analysis skills, the course discussed data sourcing and representation ethics.
